T aZZ whom, it may concern.-

Be it known that we, ISAAC N. ELLIOTT and PETTIS A. REID, of Richmond, in the county of \Vayne and State of Indiana, have invented a new and useful Improvement in Mechanical Movements, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure I is a front view of ourimproved mechanical movement; Fig. 2, a side view of the same; Fig. 3, a perspective view; Fig. 4,a plan view through line X X of Fig. 1, and Fig. a front view of a modification.

As is well known, the reel or take-up of a fabric or fence weaving machine is usually defective in its operation on account of the increased size of the fabric upon the reel justin proportion to the thickness of the fabric wound thereon, so that it is difficult to gage the speed of the rotation of the reel, and thus accommodate it to the speed of the fabric as received from the machine.

Our device relates to an improvement in mechanical movements so disposed as to be adapted for a take-up for reels or winders; and it consists of the combination, with a shaft which may be the carrying-shaft of a reel or winder, a ratchet-faced wheel, a disk at the side of the said wheel, a pawl-carrying arm journaled on the said shaft, and arod whereby said arm is connected with means for vibrating thesame, of a screw-threaded shaft mounted within the said arm,a disk upon the saidscrewthreaded shaft, bearing upon the disk upon the shaft, and a block to which the actuating-rod is connected, mounted upon the said arm and threaded to engage with the said screwthreaded shaft. By this combination of devices, as the reel or winder increases in diameter, the sorewthreaded shaftis rotated and the said bldck is moved outwardly from the shaft, thereby shifting outwardly the actuating-rod and proportionally decreasing the speed of the rotation of the reel.

In the accompanying drawings, A represents an ordinary frame, to which is journaled the horizontal shaft B, which may carry any suitable reel or winder. This shaftB is provided with a ratchetfaced wheel, 0, provided at one side with aseries of graduated retaining-pawls, D, so disposed as to prevent back movement Serial No. 258,681. (No model.)

of the ratchet-wheel O. Operatingintegrally therewith or attached at the side of the wheel C is a metal disk, E. Journaled at its inner end on the shaft B we provide a frame or arm, F, composed of two parts, G and H. Within this frame F we provide a shaft, I, journaled therein, provided almost its entire length with a screw-thread,J. The end adjoiningtheshaft B we provide with a friction-wheel, K, secured in position upon the said shaft by means of the set-screw L, so that the said friction-wheel K may be moved to or from the shaft B to adjust it inwardly or outwardly upon the face of the disk E. 7

Upon the frame F we provide a transverse piece or block, M, the ends of which have inturned lugs N, so disposed as to clasp the edges of the pieces H and G, which are thus designed to act as ways. Centrally this piece M has a threaded opening, 0, through which the threaded shaft I passes, so that in the rotation of this said shaft I the transverse piece M will be moved outwardly upon the arm F. Upon this arm Fsay near the upper end and at suitable distance therefrom along its lengthare brackets B, having slots or ways Q,in which slots or ways is placed the series of pawl-bars P, so as to be movable up or down, the lower ends of the said pawl being so disposed as to engage with the ratchet-face of the wheel C. To one end of this transverse piece M a connecting-rod, S, is attached, having a connection with the operating mechanism, by means of which power is transmitted to this device, as shown, for example, in the patent to I. N. Elliott, No. 343,232, June 8, 1886.

A modification of, the pawlPisshown in Fig. 5, wherein in lieu of the said barP and pawls D we provide eccentric clutches 'I, so disposed as to bind against the periphery of the disk E.

The operation of our device is as follows: The connecting-rod S, attached to the transverse piece M on the frame F, has a reciprocal mo tion. \Vhen itis moved toward the right, the

shaft I being effected. At every movement of the connecting-rod S the take-up of the goods wound attached to the reel is effected, and in order that the speed of the reel may be decreased just in the proportion that the goods on the reel increase in size the rotary movement of the shaft I, occasioned as the arm F moves to the right, gradually moves the piece or block M, to which the connectingrod S is attached, outwardly from the shaft B, and thus the speed of the reel is decreased.

The friction wheel K, provided with setscrew L, is so disposed as to be adjustable radially against the face of the disk E, so that it may be placed in any desired position at any distance from the shaft B to correspond with the thickness of the fabrics to be wound upon the reel to correspond with the varying speed of the device.

The piece or block M may be put in motion for a new roll or bale by rotating reversely the ratchet-wheel C until the screw carries the bar or piece to the desired point. The reverse rotation of the ratchet-wheel O is made while the machine is at rest, and is done by any simple method the operator may choose.

Having described our invention, what'we claim as new is 1. In a mechanical movement, the combination of the main shaft B, an arm, F, journaledat its inner end on said main shaft and having said arm, substantially as described.

3. The combination of the ratchet faced wheel 0, the disk E, attached to the side of said wheel, the shaft B, the'pawls D, the arm F, journaled on the shaft B, the shaft I,journaled in said frame, the friction-wheel K, adjustable by a set-screw on the shaft I,with the transverse piece M, and the connecting-rod S, and the pawl P,substantially as andfor the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands, this th day of May, 1886, in the presence of witnesses.
